To all whom it may concern.-

Be it known that I, J oHNW. OSBORNE, a

citizen of the United States, residing at Winchester, in the county ofScott and State of Illinois, have invented certain new and usefulImprovementsin Cultivators; and I do declare the followin tobe a full,clear, and exact description of the invention, suchas will enable othersskilled in the art to which it alppertains to make and use the same.

his invention relates to new and useful improvements in cultivators.

ne of the primary objects of the invention is the production of acomparatively simple and efficiently operating device of this characterhaving means whereby the plows may be regulated to run at the desireddepth in the ground.

A further object of the invention is to equip the machine with simplemeans'under the control of the operator whereby the several gangs ofplows may be raised clear of the ground in such cases where this wouldbe desirable, as in turnin at the end of the rows, or in going to anfrom the field to be plowed.

With these objects in view, the invention consists of certain novelfeatures of construc tion, combination and arrangement of parts as willbe described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a view in side elevation of acultivator constructed in accordance with the invention, parts beingbroken away to more advantageously illustrate certain features of thein- V vention; Fig. 2 is a plan view of Fig. 1 Fig. 3

is a vertical section taken through the draft beam in front of thepressure sprin s for the plow beams, looking to the rear; ig. 4 is avertical section taken through one of the connections for the axle andmachine frame. Fig. 5 is a detail pers ective view of a portion of themachine fl ame and cooperative parts; and Fig. 6 is a detail perspectiveview of the lifting lever.

Referring to the drawings, which are for illustrative purposes only,and, therefore, are not drawn to scale, 1 indicates the main orsupporting wheels of the cultivator, and 2 the machine axle, which is ofbowed or a proximately inverted U-shaped form. T e

machine frame 3 is of approximately U- shaped form, and is arranged withits cross member 4 disposed at the front of the machine, to which crossmember is connected the inner or rear end of the draft tongue or beam,5. The axle of the machine is formed from hollow tubing, having theirends connected at points suitable distances above the hubs of thesupporting wheels by vertically disposed 1 transversely aperturedbearing members, 6, and the frame of the machine, 3, is also formed fromhollow tubing or castings having their ends connected by correspondinglongitudinally disposed bearing members, 7, adapted to bear or workagainst the inner faces of the'members 6, and having central transverseapertures, 8, adapted for registration with the apertures of the former.Pivot members, 9, preferably in the form of bolts, are passed orextended through the apertures ofthe bearing members, 6 and 7,respectively, and have screwed on their outer or threaded ends fasteningnuts, 10.

From the arrangement above described, it will be readily perceived thatthe U-shaped supporting axle of the machine may be swung eitherforwardly or rearwardly in a vertical plane and thereby permit of theframe 3 being raised or lowered, as desired.

, In carrying out the invention, a transversely disposed tubular member11 is fixedly mounted on the machine frame 3, a suitable distance inrear of the axle of the machine and has fixed on its central orintermediate portion an upright locking member, 12. A longitudinallydisposed operating lever 13 is connected at its front or forward end tothe center or intermediate portion of the cross member 14 of thesupporting axle, and has formed in its upper edge near its rear or innerend a plura ity of longitudinally spaced locking recesses, 15, adaptedfor lock ing engagement with the upper wall of an aperture or opening,16, formed near the upper end of the locking member 12 for the passageor reception of the operating lever. A spring, 17, is fixed to the rearside edge of the member 12 and has its rear end disposed in a commonplane with the operating lever, 13, and arranged to exert an upwardpressure on the rear or recessed end of the same, the tendency of whichis to, 1naintain;one of the locking recesses of the operating member inlooking engagement w1th the upper wall of the aperture 16 of the lockingmember 12.

From t is arrangement it will be seen that by a proper manipulation ofthe operating member 13, the supporting axle 2 may be swung in avertical plane, and the machine,

tening devices, is a transversely disposed supporting member, 18, whichis preferably formed from a tubular casting, and depending from the endsof this member are two vertically disposed laterally spaced hangers, 19,also of preferably tubular form. Two vertically disposed supportingmembers, 20, are connected at their upper ends with the side members ofthe machine frame 3, and arranged between the lower ends of thesemembers and the members, 19, are transversely disposed members, 21. Alongitudinally disposed plow beam, 22, is pivotally connected in anysuitable manner with each of the members 21, and each of these beamscarries a gang of plows, 23, at its rear end. Each of said-beams is alsoprovided at its rear end with a cutting disk, 24, of :any desiredpattern, which is spaced laterally and arranged slightly in advance ofits gang of plows, 23.

A lifting lever, 25, comprising an obliquely disposed handle, 26, aforwardly extending longitudinally slotted arm, 27, and an arm, 28,which is disposed at a-suitable angle with the arm 27 and provided'withalaterally extending pin or offset, 29, at its outer end, is pivotallymounted near each end of the member 10. The slotted arms 27 of thesemembers are connected with the 11 per ends of vertically disposedconnecting links or members 30, connected .at their lower ends with theplow beams, 22, and the pins or offsets 29 of the arms 28 connect withthe rear ends of longitudinally disposed springs, 31, fixed or fastenedat their front ends to the machine frame in any suitable manner. Theselevers 25 are employed to raise the plow beams 22 above the ground insuch cases where it is de sirable, as in turning at the ends of therows, or ingoing to or from the field, and, in raising the plow beams,the springs 31 cooperate with the operator because of the fact that theyare arranged to normally exert a forward pull on the arm 28 of the lever.25. A spring, 32, having a'straight, longitudinally disposed,rearwardly extending portion, 33, at its upper end is adjustablyconnected at such portion with a casting, 34, fixed near each end of theend portion of the machine frame, 3, which spring is bent intermediatelyof its ends and at a point in advance of its point of attachment to forma plurality of coils, and is then extended rearwardly and connected atits extreme rear bent end, 36, with each of the plow beams, 22. Thetendency of these springs, as will be readily perceived by examinationof the drawings, is to maintain a downward pull on the plow beams andthereby keep the plows in the ground.

A chain 37 is connected at its rear end to each of the verticallydisposed members 20 and "at its forward end near one end of thedoubletree, 38, sustained by the beam 5, said doubletree being equippedwith the usual swingletrees, 39.

The numeral 40 represents a seat which is mounted on the machine frameat a suitable point in rear of the supporting wheels and in position topermit of the arms 26 of thelifting levers to be easily grasped by theoperator.

By constructing the frame of the machine of tubular castings, ormembers, it will be seen that while the machine is of exceedingly lightweight, and, therefore, more easily drawn by the draft animals, itpossesses con siderable strength. and is adapted for rough usage withoutits parts becoming deranged or inoperative. A

Having thus fully described my invention, what I claim as new and desireto secure by Letters-Patent, is:

In a machine of the character described, the combination with thesupporting wheels, of a bowed axle, a U-shaped frame pivotally connectedto the vertical portions of said axle, an upright lock-ing member havingan aperture near its upper end, fixedly mounted on the frame in rear ofthe axle, a longitudinally disposed operating member connected with thecentral portion of the axle and having a plurality of spaced lockingrecesses formed in its upper edge for engaging the up er wall of thelockin member aperture, and a resilient element 'xed to the lootingmember for maintaining one of the locking recesses of the operatingmember in locking engagement with the aperture of the locking member.
